Just a quick follow-up to my two previous posts regarding recent and future Apple products.

Again, as best-illustrated by Apple’s official iPhone / Touch applications – iTunes Remote, Keynote Remote, iDisk, and now, Gallery – there’s a definite, purposeful limitation to the tasks the applications perform.

Each MobileMe-specific application in particular, only focuses on one aspect of the MobileMe service: iDisk and Galleries.

Apple could have easily released an all-in-one MobileMe app, but they didn’t.  They could also just as easily bundle the free apps with the device, but again, to maintain simplicity, they’ve – so far – chosen not to.  It’s up to the user to install (enable) them as necessary.

These are, of course, good design decisions.  But I think they’re much more than that too.
